Sorry, that is completely false. druntime was created specifically to 
allow Phobos and Tango to co-exist. At the time, almost all of the code 
in druntime was written by Sean, and he was leading the Tango runtime 
development. The expectation was that Tango would continue to use Sean's 
runtime, it was just in a separate project.

Sean took all the code he had written. The other minor contributors did 
not yet give permission for their code to be used, so of course it could 
not be included.
